Gergő Tisza 7afbc5ce92 Use provider XHR information in performance metrics + several fixes
* more robust method of obtaining URL
* decouple performance logging from providers (mostly)
* ignore fake XHR object which jQuery returns for JSONP requests
* guard for CORS requests - apparently Chrome refuses to return
  certain information even with an Allow-Origin: * response header.
* Resource Timing is limited to 150 results, which causes fake
  misses in debug mode. There is an API to increase the limit
  but it is not implemented in Chrome. I am calling it nevertheless,
  maybe IE understands it (it is present in the MSDN docs at least).

This seems to work for AJAX, CORS, JSONP, image AJAX; CORS requests
return 0 for a lot of values, per spec a Timing-Allow-Origin: *
header might help that.

Gilles Dubuc 6e127b25e2 Preload prev/next images
When the lightbox is opened, or prev/next pressed, preloads the
previous/next N images.

Technical debt introduced:
* initialization is a mess, with the viewer and the interface
  randomly setting properties on each other in different phases of
  execution. That got in the way and I shuffled things around
  until they worked, which is obviously not the way to have a
  robust system, but hopefully it will get scrapped soon anyway
  in favor of a clean top-down dependency injection.
